I currently have two DE and one HE campaign stuck due to this, my Skaven and Repanse campaign worked fine but now the game just derps out for a lack of a better term.
I use cosmetics mods sorted via a mod manager to avoid conflicts.
I have already tried running clean non-modded game, I have also reinstalled steam.
I realise its the holidays but please sort this as every campaign is a ticking time bomb before it goes tits up.
Again I realise its the holidays so happy holidays and I hope you can get this sorted.
